INTRODUCTION: Cartilaginous tumors of the mid-face and the skull base are rare. CASE REPORT: For the first time, a case report of a chondroma of the base of the ear in a 56-year-old woman is presented. In 1974 the patient developed a facial nerve paralysis while she was pregnant. Twenty-two years later the patient developed persistent headache and CT studies of the head were obtained, which showed an extensive tumorous lesion located at the base of the ear. A tumor was resected through an otoneurosurgical approach. The histological examination showed a chondroma. CONCLUSIONS: Even the rare diagnosis of a chondroma should be considered for a differential diagnosis of skull base tumors.
Cartilaginous tumors of the larynx are rare; although chondromas are the most frequent of these tumors. Laryngeal chondrosarcomas are even rarer, in spite of this being the most frequent histological variety of sarcoma (less than 1% of all malignant laryngeal tumors). These tumors are slow-growing, locally aggressive, and tend to recur. They are less aggressive in the larynx than in other sites: cervical or distant metastases are rare (8.5%) and recurrences often can be controlled. The most common presenting symptom is hoarseness with normal indirect laryngoscopy. The complementary studies of choice are computed tomography (CT) and magnetic resonance imaging (MRI). The role of these imaging techniques in the study of laryngeal chondroma and chondrosarcoma was examined. These sporadic tumors may be overlooked, although early identification is necessary for effective treatment.
BACKGROUND: Only seven cases of cartilaginous tumors of the skin have been described in the dermatologic literature. OBJECTIVE: We studied the nature of cutaneous cartilaginous tumors and their clinical spectrum. METHODS: We describe a 56-year-old woman with a superficial cartilaginous tumor of the sole of the foot. The tumor appeared to be a cutaneous mass and was resected. RESULTS: Histologically, the tumor extended from the dermis to the subcutaneous tissue. Despite the presence of foci of nuclear changes that suggested a malignancy, there has been no recurrence in the 3 years since its removal. Our review of previous reports indicated that this case may have been a soft tissue chondroma. And it confirmed that cutaneous cartilaginous tumors comprise a superficial soft tissue chondroma and a true cutaneous chondroma primarily located in the dermis. CONCLUSION: Our case appeared to be a cutaneous cartilaginous tumor. A complete local removal is the treatment of choice.
